The Yin to Jack Black's Yang in the greatest rock band ever concieved and together the two are called: Tenacious D. The man with the golden fingers, the man who wears sweat pants during performances, the man who can kill a Yak from 200 yards away... with mind bullets!
The man with the power... to move you.

JB: Just don't want to.
KG: Yes.
JB: Would you take a bullet for me?
KG: No.
